SPECIFICATION forming part of LettersPatent No. 652,572, dated June 26, 1900.

Application filed April 13, 1899.

Serial No. 713,501- (No modeL) T0 (bZZ whom, it mag concern.-

Be it known that I, SIMON W. WARDWELL,

J r., a citizen of the United States, residing in the city and county of Providence, in the State of Rhode Island,have invented certain new and useful Improvements in Winding- Machines, of which the following is a specification.

My invention relates to devices for winding conical cops and to'providing means wherebyhereinafter and shown in the accompanying drawings, in which'- 3 I Figure 1 is a front view of a winding-machine with my new coning device attached. Fig. 2 is a side view of the same. Fig. 3 is a sectional view of the coning device, taken on line 7 7. Fig. at is a View of an attachment for adapting the cone-spindle for winding cylindrical packages. Fig. 5 is an end View of same. Figs. 6, 7, 8,and 9 show details of the construction.

The coning device is similar to the one described in Patent No. 562,263 in that it is supported on the winding-spindle with its axis so inclined thereto in a horizontal plane that the element of the cone along which the traversing guide travels is parallel to the line of travel of said guide. Ihave, however, made improvements in the structure set forth in said patent-+notably, in providing improved means for securing in place the paper cone or tube on which the material is wound, in providing means for taking up the wear between the tube-carrier and its bearing, in the arrangement of the gearing, and in other features which will be indicated in the specification.

I preferably describe my invention as applied to a machine such as is described in Letters Patent Nos. 536,672 and 567,871, in which thewinding-spindle and the traversing guide are so connected that the relative speed of the two can be adjusted for the size of material to be wound. As the structure of these machines has been fully set forth in the Letters Patent above referred to, I will not repeat a description of them, but will confine myself to adescription of the devices referred to in this specification.

Upon the rotating spindle 9 is temporarily supported the cone member or hearing K, prevented from turning with or about said spindle by means of the pin 28, extending into a hole in the frame A of the windingmachine andfastened therein by means of the screw 27. In order that the pressure of the screw 27 upon the pin 28 shall not force the member K against the winding-spindle, thereby causingundue friction, I pivot said pin to the bearing K by a pin 28, so as to Imove slightly on the pin 28 to and from the winding-spindle.

r The aXisof the member K does not correspond with that of the spindle 9, but is inclined thereto at such an angle that each element of the cone-tube or of the cone-package being wound shall when rotated between the spindle and the traversing guide i be substantiallyparallel to the line of travel of said guide.

Upon the bearing K is carried and rotates the conical sleeve or tube-carrier B, driven from the spindle 9 by means of an internal bevel or crown gear 40, which is attached to the spindle by means of the screw 41 and the dowel-pin 40. The teeth of the pinion mesh with corresponding teeth in the sleeve B equal in number to those in the pinion, so that the sleeve B makes the same number of rotations as the spindle.

To permit the sleeve B to run freely and smoothly without excessive play and to adjust it to take up wear, the member K is jpushed toward the pinion 40 until the play .is eliminated and is held firmly against longitudinal movement by means of the pin 28 and the screw 27, which extends through an opening in the frame and bears on an inclined face or seat on the side of the said pin. This inclined seat is provided because in pushing the cone tubes onto the carrier 13 the tendency is to force the bearing K away from the pinion, thereby causing or increasing play between the sleeve B and the mem ber K. With the pin beveled, as indicated,

it is impossible to force the member K back without first loosening the screw 27. Other means to effect this result may be employed.

To insure that the bearing-surfaces between the spindle 9, the sleeve B, and the member K shall be maintained Well lubricated, I provide in the member K suitable chambers 22 and 23, which are filled with an absorbent adapted to retain a quantity of oil and deliver it to the bearing-surfaces as needed. Oil is introduced into the device through a suitable hole, as the hole 15 in the stem Z of a detachable cap L, which is suitably adapted to the tube-carrier and constitutes a prolongation thereof. device rot-ates the oil works back through the gearing, along the spindle 9, and between the member K and the tube-carrier B,

lubricating the surfaces and replenishing the oil-chambers. As some of the oil will work out at the rear or base of the carrier B, I provide a guard O, which serves to intercept any drops which may be thrown off by the centrifugal action which is incident to the high speed at which the tube-carrier B rotates. This is a very desirable feature, inasmuch as the winding-machines are set side by side, and anyoil thrown from one winding-spindle will spatter and damage the package being wound on the spindle next adjoining.

The outer surface of the tube-carrier B is provided with longitudinal corrugations to hold the paper cone tube from slipping rotatively. To prevent the tube from slipping longitudinally, I use the split ring G, encircling the tube-carrier or otherwise arrangedand circumferentially corrugated or otherwise provided with a retaining-surface and adapted to be expanded. A sleeve II is adapted to slide on a stem 1 of the cap Land is adjusted thereon by means of the screwj, adapted to an internally-threaded axial hole in said stem. The cap L at 26 and the sleeve II at 25 have suitably-beveled bearing-faces to correspond with an internal taper or bevel at each end of the split ring G, so that the ring can be expanded or contracted by changin g the relative positions of the bearing-faces.

I do not limit myself to a corrugated ring,

, though a ring provided with a continuous spiral corrugation, as shown, is preferably adapted by use. The object of this corrugation is to adapt the ring to make a firmer contact with the paper tube. This can be attained in several waysas, for instance, by making a ring with a knurled surface or by forming on the surface a series of circular rings.

The screwj is provided with a knurled head which, abutting the end of the sleeve H, advances the latter along the stem Z, thereby expanding the split corrugated ring G and imparting to it at the same time a slight linear movement toward the base of the cone. As the ring expands the tops of the projections or corrugations are forced into the tube, and the linear movement of the ring tends to press the tube more firmly upon the longitudinal corrugations. \Vhen the screw j is loosened, the ring G contracts, due to its elasticity, forcing back the sleeve H and leaving the As the coming tube on the package wound free to be removed.

When the coning device is in operation, the end of the screw j obstructs the oil-hole i, so that no oil can leak out. When it becomes desirable to oil the device, the screw 3' is withdrawn sufficiently so that the split ring may be drawn back to uncover the oil-hole t and render it accessible.

The new arrangement of gearing herein described is greatly superior to that previously employed in that larger and stronger gears can be used, reducing backlash and the extent of play at the periphery of the package. Furthermore, when, with the previous construction, the teeth of the gears became dam aged it was necessary to replace the whole spindle 9. With the present construction it is necessary to replace only the pinion 40 or the tube-carrier B, either of which is a less expensive piece than the spindle 9.

When desired, the same machine can be readily adapted to wind cylindrical packages as follows: A tube holder for cylindrical tubes is secured by extending the spindle 9. One means consists in the use of a section 20, Fig. 4, adapted to be suitably attached to the spindle 9, as by means of a screw portion 20, which fits the hole provided for the pinionscrew 41. The arrangement for holding the tubes is a part of the section 20 and is of a construction commonly employedthat is, the end of the holder is split and adapted to be expanded by means of a screw 21. Ahole 20 is provided for a suitable wrench, whereby the tube-holder can be turned to bind it securely to the spindle 9.

While I have shown the parts H Gj in connection with the other parts, the latter may be used alone or with other means for prolonging the holder and for securing the conetube thereon.

Without limiting myself to the precise construction and arrangement shown, I claim* 1. The combination in a Winding-machine, of a winding-spindle, a cone-tube carrier, means for driving said tube-carrier from the spindle, and a bearing for said tube-carrier adjustable longitudinally on the spindle, and means for securing the bearing after adj ustment and for holding it from rotation, sub-- stantially as set forth.

2. The combination in a winding-machine, of a winding-spindle, a cone-tube carrier connected to be driven from said spindle, a conical bearing for said tube-carrier supported on the spindle, and a pin flexibly attached to said bearing and longitudinally adjustable on the frame of the machine, and affording means for retaining the tube-carrier in its longitudinal position on the spindle, substantially as set forth.

3. The combination in a winding-machine, of a winding-spindle, a cone-tube carrier connected to be driven from said spindle, a conical bearing for said tube-carrier supported on the spindle, and a pin, flexibly attached to said bearing, and provided with an inclined seat, and a screw bearing on said seat, substantially as set forth.

4. The combination in a winding-machine, of a winding-spindle, a cone-tube carrier, a non-rotatable conical bearing for said conetube carrier supported on the spindle so as to be longitudinally movable thereon, and means for retaining the bearing in position on the spindle after longitudinal adjustment, and for rotating the carrier on the bearing, substantially as set forth.

of a winding-spindle, a cone-tube carrier, a cone-bearing for supporting the cone-tube carrier, means for supplying oil between the two, and an oil-guard at the large end of the cone-tube carrier, substantially as described.

6. The combination in a winding-machine, of a winding-spindle, a cone-tube carrier havin glon gitudinal corrugations and constructed to be expanded at one point and provided with circumferential corrugations at said point, means for expanding and contracting the part of the device having circumferential corrugations, and means for connecting said tube-carrier to turn with the spindle about an axis at an angle to that of the spindle, sub stantially as set forth.

7. The combination in a cone-tube holder, of means for preventing the tube from slipping rotatively, a split ring adapted to e11- gage with said tube, and means for expanding said ring and imparting thereto a linear movementto force the tube against the holder, substantially as set forth.

8. The combination in a winding-machine, of a Winding-spindle turning in fixed bearings, means for positively driving said spindle, a traversing guide traveling parallel to the axis of said spindle, and means whereby said winding-spindle can be adapted to retain and wind either cylindrical or conical packages, substantially as set forth.
